Evaluation of serum level of Osteocalcin hormone in male infertility

摘要

The suggested concept of "bone as an endocrine organ" had shed the light on the role of osteocalcin, an osteoblast secreted hormone, in regulation of testosterone production. This study aimed to assess the association between the active undercarboxylated form of osteocalcin (ucOC) and semen parameters and hormonal levels in infertile male patients. The study was carried on 34 infertile male patients and 20 fertile healthy control males. Semen analysis and serum level of testosterone, LH and FSH were performed in addition to serum level of ucOC in cases and controls. The results revealed significant differences between cases and controls in all measured semen and hormonal parameters. In addition, significant higher level of ucOC in cases than control group (p =.019). On the other hand, ucOC was not related significantly to any of the measured hormones or semen parameters. There was no significant correlation between ucOC and sperm concentration, total motility, morphology (p = .594, .640, .940 respectively) and similarly between ucOC and testosterone level or LH level (p = .275, .954 respectively). The significant higher level of ucOC in infertile cases cannot be used as a predictor of male reproductive parameters.
